Material: Made from composite material such as Glass Fiber, Resin, Quartz, Corundum & so on.

Structure:

Using the structure of pot bottom style (loading equally), the strength supporting area will extend by more than ten or dozens of times. Therefore, the ability of strength sustaining will be more excellent.

Design:

Infusing the manhole covers with the art of relief sculpture, designing individually to meet clients's demands with artistic effect.

Advantages:

1) Environmental Protection/"Green"
